Description

Technical Field

[0001] The utility model belongs to the technical field of material processing, in particular to a sample loading plate used for grinding and polishing square samples. Background Art

[0002] To test the bending strength of ceramic materials, the four sides of the square specimen in the length direction need to be polished and ground. For larger grinding surfaces, hot wax or rosin is usually used to bond the sample under the sample tray for grinding. Since the height of the square specimen is small, only 3 cm, it is difficult to fix it on the sample tray when grinding the sides corresponding to the length and height. The worker needs to hold the square specimen in his hand and press it on the grinding disc of the polishing machine for grinding, which is not only time-consuming and labor-intensive, but also poses a safety hazard.

[0003] Based on this, the existing technology needs to be further developed. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0023] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0024] According to an embodiment of the utility model, a sample loading plate for grinding and polishing square samples is provided. Figures 1 to 3 , including a sample tray body 1 and a fixing component. The connecting end 2 of the sample tray body 1 is detachably connected to the coupling of the polishing machine. A groove 3 for accommodating a square sample is provided on the sample tray body 1. The size of the groove 3 is larger than the size of the square sample. The fixing component passes through the side wall of the groove 3 and fixes the square sample inside the groove 3.

[0025] It should be noted that the square sample is fixed in the groove 3 of the sample loading plate by a fixing assembly, and at the same time, the square sample is pressed onto the grinding disc of the polishing machine for grinding by means of the weight of the sample loading plate body 1. Thus, the square sample can be fixed on the sample loading plate body 1 for grinding of the four grinding surfaces. There is no need for staff to grind by hand, which saves time and effort and reduces safety hazards.

[0026] In the sample loading plate for grinding and polishing square specimens of the present embodiment, the fixing assembly includes a fastener 4 and a protective pad. A threaded hole is provided on one side wall of the groove 3, and the fastener 4 passes through the threaded hole to abut against the square specimen. The protective pad is located at the end where the fastener 4 abuts against the square specimen to prevent the square specimen from being scratched by the end of the fastener 4.

[0027] In the sample loading plate for grinding and polishing square samples of the present embodiment, the protective pad is made of elastic materials such as rubber, silicone, polyurethane, etc.

[0028] In the sample carrier plate used for grinding and polishing square samples in this embodiment, the sample carrier plate body 1 is configured as a disc-shaped structure, and a plurality of grooves 3 are provided. The plurality of grooves 3 are arranged along the circumference of the sample carrier plate body 1, so that multiple square samples can be ground simultaneously, thereby improving work efficiency.

[0029] In the sample loading plate used for grinding and polishing square samples of the present embodiment, in order to facilitate the setting of the fixing component, the extension direction of the groove 3 is at an oblique angle to the radial direction of the sample loading plate body 1, and a notch is opened on the edge of the sample loading plate body 1 to form a fixing groove 5, and the threaded hole is located on the side of the fixing groove 5.

[0030] In the sample loading plate for grinding and polishing square samples of this embodiment, the fixing groove 5 is a fan-shaped groove, and the central angle of the fan-shaped groove is not less than 90 degrees, so as to prevent the fastener 4 from interfering with the side wall of the fan-shaped groove.

[0031] In the sample carrier plate for grinding and polishing square samples of this embodiment, the depth of the groove 3 is smaller than the thickness of the sample carrier plate body 1 and smaller than the thickness of the square sample, so as to ensure that when the square sample is placed in the groove 3, the surface to be ground of the square sample protrudes from the sample carrier plate body 1.

[0032] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
